摘要:

根管治疗的主要目的是清除感染根管内的微生物。氢氧化钙具有抗菌、溶解坏死组织、抑制牙根吸收、诱导硬组织形成、不良反应少等生物学特性,因此使用氢氧化钙进行根管内封药是临床常用的感染控制方法之一。由于根管系统解剖结构复杂、氢氧化钙赋形剂及冲洗方式的影响,根管内的氢氧化钙难以完全清除。残留的氢氧化钙会降低根管充填的密闭性及牙齿的抗折性,影响根管治疗的成功率。本文将就导致氢氧化钙残留的因素、氢氧化钙残留对根管治疗的影响作一综述。

Abstract:

Root canal treatment mainly aims to eliminate microorganisms from the contaminated root canal system. Calcium hydroxide have anti-bacterial properties, can dissolve necrotic tissue, inhibit root resorption and induce hard tissue formation and has little side effect. Thus, calcium hydroxide as an intracanal medicament is commonly used to control root canal infection in clinical practice. However, considering the complex anatomy of the root canal system and the influence of calcium hydroxide vehicles and irrigation equipment, the complete removal of calcium hydroxide in root canal is hard. The residual calcium hydroxide influences the sealing of root canal filling and reduces the fracture resistance of teeth. Therefore, the success rate of root canal treatment is influenced. This paper reviews factors leading to the residual of calcium hydroxide and the influence of residual calcium hydroxide on root canal treatment.

Key words: calcium hydroxide, root canal treatment, infection control
